Quick TakeStrap yourself in for a wild ride through horological architecture! The Flying Grand Regulator Skeleton isn't just a watch; it's a mechanical metropolis on your wrist. Chronoswiss went full-on structural engineer here, stripping away everything but the essential beauty of the C.677S movement. Forget a simple dial; this piece boasts a multi-level cityscape – skeletonized base, numbered mid-level, and a galvanic black top floor screwed onto sturdy blocks. Watching the thermally blued screws and skeletonized gears whirl beneath the off-center hours and central minutes is pure mechanical theater. The hand-bent minute hand adds a touch of artisanal flair, tracing its path above the small seconds ticking away down south at 6 o'clock. Limited to just 30 pieces, wearing this isn't just telling time; it's owning a numbered piece of kinetic art, all wrapped up in a robust 44mm steel frame with that signature onion crown and knurled bezel. It’s a conversation starter that barely needs an introduction.

DescriptionThe Chronoswiss Flying Grand Regulator Skeleton, reference CH-6723S-BKYE, features a case constructed from stainless steel, comprising 21 individual parts. Its physical dimensions measure 44mm in diameter and 12.48mm in height, accommodating a strap width of 22mm. Case finishing incorporates both polished and vertically satin-finished surfaces, complemented by a characteristic onion-style crown. Securing the front is a polished screw-down bezel, engineered with a full thread and side knurling, housing a curved sapphire crystal treated with an anti-reflective coating. The case back is a screw-down design, featuring a satin finish and an integrated sapphire crystal for movement observation. Water resistance is rated at 3 bar, equivalent to approximately 30 meters, providing protection against incidental water contact.

Internally, the timepiece is driven by the manual winding Caliber C.677S movement. This mechanism operates at a frequency of 2.5 Hz, translating to 18,000 alternations per hour (A/H), and contains 17 jewels. When fully wound, it offers a power reserve of approximately 46 hours. Movement finishing is extensive: the pallet, pallet-wheel, and screws are polished. Key structural components, namely the plate and bridges, undergo skeletonization and are finished with circular graining. Further detailing includes skeletonized gear wheels and screws treated with thermal bluing for color and corrosion resistance. The dial architecture is notably complex, built upon several levels. It starts with a skeletonized base incorporating a funnel structure. Above this sits a middle level where the unique limitation number (out of 30) is hand-painted. The top level is galvanic black and secured onto foundation blocks via screws. Time indication follows a regulator format: off-centre hours are displayed at the 12 o'clock position, minutes are indicated centrally, and a small seconds subdial resides at 6 o'clock. The "Poire Stuart" hands are lacquered and curved, with the minute hand specifically bent by hand.
